It’s not surprising that our modern medicines can be made from plants. For the most part. That’s where they originally came from.
Other then that you can make a bunch of stuff. The thing you have to be careful of is quality control. When you picked can make the difference between something that is not strong enough, just right and "oops you're dead".
People say, "well it's natural". So is nutmeg. It can be used to make your food taste nice, a bit more and it can send you on a trip I have been told is most unpleasant and a bit more then that and you are saying hello to St Peter.
It is like distilling (which is where the name "Still Room" came from) you can make something very good that will help keep you alive or you can make poison. And at the same time.
So be careful is all I am saying.
